| Belzona Elastomer Used To Repair Torn Conveyor Belts At Recycling Plant | | | Industry:General Industry (GIND) | | | Application:Solids Handling Machinery (SHM) | | | Customer Location:Recycling Plant - Zurich, Switzerland | | | Application Date:April 2019 | | | Application Situation:A recycling plant specialising in urban mining, extracting and reusing building materials from previous sites e.g. concrete. At the facility, a large conveyor belt had become caught on a defective scraper, causing a linear tear over 32m along the rubber. | | | Problem:Straps of the conveyor belt had been replaced on a few weeks earlier and the client had no replacements in stock. This damage had occurred on a conveyor belt in the stage of the recycling process, during a busy period of the year. Therefore, the conveyor belt needed to be repaired as soon as possible. | | | Products:Belzona 2311
Belzona 9341
Belzona 2911
Belzona 9111 | | | Substrate:Reinforced rubber | | | Application Method:The application was carried out in accordance with Belzona Know-How System Leaflet SHM-1. Any loose parts of the rubber were first cut away, before the substrate was prepared using a rotary wire brush. The entire area was subsequently cleaned using Belzona 9111. The defected areas were masked off and conditioned, before Belzona 2311 was applied to the surface. This is a fast-curing material that is cold-curing and requires no specialist application tools. To reinforce the repair Belzona 9341 (a flexible and strong farbic mesh) was embedded into the elastomer and then encapsulated with a secondary application of Belzona 2311. | | | Belzona Facts:Due to the fast turnaround required, the Distributor carried out the repairs on the same day. The application took 7 hours to complete compared to replacement, which would caused approximately 3 times the amount of downtime. This allowed the plant to run the conveyor belt the very next day. This belt is still in use after 9 months without any problems at the repair points. | | | Photographs Description
